Question

VA ROG REPEDE CA DAU CORONITA!!!!!!!​

Answer 1

a + b + c + d = 123

b = a + 8

c = a + b = a + a + 8 = 2a + 8

d = a + 7

inlocuim tot in suma initiala

a + a + 8 + 2a + 8 + a + 7 = 123

5a + 23 = 123 ==> 5a = 100 ==> a = 20

b = a + 8 = 28

c = 2a + 8 = 48

d = a + 7 = 27

Answer 2

Explicație pas cu pas:

b= a+8

c= a+b

d= a+7

a+b+c+d=123

123-23=100

a= 100÷5=20

B= 20+8=28

c= 20+28=48

d= 20+7=27

spor !!!!
